Absolutely! I had a vet that used to work for Purina or something like it. She helped to develop one of the dry foods. After she became a vet and her own cat got diabetes, she was adamant about not feeding dry food, even the one she created!
I think the realization of how bad dry food really is for cats came slowly, and is still ongoing. My last cat developed diabetes, too, and his food was likely the cause of it. Next time I'm going for one of the all-protein foods.
